Hazel Turner

Senior Associate

Hazel has a wealth of experience handling a diverse range of chemical subject-matter which includes pharmaceuticals, industrial chemistry, and consumer chemistry. She particularly focuses on small molecule pharmaceuticals, formulations and new solid forms, as well as dosage regimens including those for combination therapies. Hazel is highly experienced in prosecuting patent applications at the European Patent Office and her practice extends to defending and opposing patents in post-grant opposition proceedings, as well as overseeing the filing and prosecution of pan-European supplementary protection certificates (SPCs). She is also adept at preparing validity opinions and carrying out freedom to operate analyses across a range of chemical subject-matter.

Hazel qualified as a UK and European Patent Attorney in 2013, after joining Carpmaels & Ransford in 2008 and she obtained the Intellectual Property Litigation Certificate in 2015.

Prior to joining the patent profession, Hazel completed a PhD in organic chemistry at the University of Manchester. She also graduated from the University of Oxford with an MChem degree. During her PhD, she studied molecules which display axial chirality, and in particular, worked on the synthesis of novel atropisomeric diarylurea compounds, utilising organolithium chemistry. Part of Hazel’s research was carried out within the pharmaceutical industry and her research has led to several publications in peer-reviewed journals.

Away from the office, Hazel is a mentor for the Social Mobility Foundation which is a charity which supports young people with the aim to make a practical improvement in social mobility. In her spare time, Hazel enjoys Ballroom and Latin dancing which is a hobby she takes joy in practising when holidaying on cruise ships. She is also a keen swimmer and loves leisurely exploring new locations on foot.

“Hazel has a depth of knowledge that we tap into constantly regarding pharmaceutical patents.”
